MAX5019 Datasheet Current-mode Pwm Controllers With Integrated Startup Circuit

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2115; Rev 0; 7/01 Current-Mode PWM Controllers with Integrated Startup.

General Description

The MAX5019/MAX5020 integrate all the building blocks necessary for implementing DC-DC fixed-frequency power supplies.

Either primary- or secondaryside regulation may be used to implement isolated or nonisolated power supplies.

These devices are currentmode controllers with an integrated high-voltage startup circuit suitable for telecom/industrial voltage range power supplies.
